The Delta knee pad is constructed from a breathable perforated and tougher Duratex neoprene with air plush lining for maximum comfort. The back side of the pad uses a dual layer Lycra design, that is soft on the inside but strong and durable on the outside. To protect your knees from impact we use our DFS system foam under a polyamide soft cap, with additional padding for side impacts. A Sharkskin neoprene inner section ensures the pad stays firmly in place.
